Spy Hunter is a vertical scrolling action/driving game with the player in the role of a spy driving an armed sportscar. The object of the game is to travel the freeway destroying as many enemy vehicles as possible while protecting civilian vehicles. The game uses top-down perspective.
The game begins with the player driving the fictitious G-6155 Interceptor. Various enemy vehicles try to destroy the player's car or to force it off the road, including a helicopter that drops bombs from overhead. A counter increments the score while the car is moving and on the road. Additional points are earned destroying enemy vehicles using weapons or by forcing them off the road. After an initial lead-in time during which the player has an unlimited supply of cars, the player must earn extra cars by obtaining high scores. Destroying non-enemy cars halts the score counter for a short while, and no points are scored whenever the player's car is off the road. The car can be destroyed by a hard collision with another vehicle or if it is hit by an enemy weapon, including the craters blasted into the road by the helicopter's bombs.
Following periodic forks in the road, players can enter a new 'territory' with different terrain and/or weather conditions. Players can also upgrade the car's standard machine guns by adding other weapons by entering the Weapons Van, which appears in each new territory and can be periodically summoned by pressing the blinking 'Weapons Van' button. Three special weapons are available: oil slicks, smoke screens, and surface-to-air missiles. Each has limited ammo and are lost if the player's car is destroyed. The game's dashboard shows which weapons are available, when lit.
It is possible for the player to convert the car into a go-fast boat for brief periods by driving through a special boathouse which appears infrequently at the side of the road after which the player is attacked by two different enemy boats.

Originating in the arcades, Spy Hunter is a driving action game played from an overhead point of view. Your car is equipped with machine guns to help you get past the numerous enemies out on the road (be careful not to shoot any civilians, though!) Occasionally you will come across a weapons van, and if you drive into the back of the van your car becomes equipped with a second weapon (such as smoke screen, oil slick, or missiles). At several points the road splits and you can enter a boathouse which transforms your car into a boat temporarily. If you drive far enough the seasons change as well (watch out for icy conditions during winter!). The enemy cars will do anything to stop you, including running you off the road, firing guns from the back of a limo, or dropping bombs from a helicopter.
